Description

通信终端设备和数据传输方法 Communication terminal device and data transmission method

技术领域 FIELD

本发明涉及一种通信终端设备和一种数据传输方法。 The present invention relates to a communication terminal apparatus and a data transmission method.

背景技术 Background technique

近年来,象移动电话和固定终端这样的通信终端上的应用程序的复杂性已被大幅增加以支持各种电信业务。 In recent years, as the complexity of the application of such a communication terminal on the mobile phone and fixed terminals has been a substantial increase in support of a variety of telecommunications services. 因此,着重于位于应用程序和呼叫处理器之间的通信终端(中间件层(middleware layer)),这种通信终端根据来自应用程序的命令执行电路连接控制,并且减少应用程序的电路连接控制的开发负担(development load)。 Thus, focusing on the communication terminal is located (middleware layer (middleware layer)) between the application and the call processor, such a communication terminal performs a circuit connection control according to a command from the application program, the application and reduce the circuit connection control development burden (development load).

也就是说,例如,理想情况下,象浏览器和邮件器这样的应用程序应该可以使用与电路连接控制无关的、包含TCP(传输控制协议)和IP(Internet协议)的特定协定来执行通信。 That is, for example, the ideal case, the mailer and the browser as such applications should be able to perform communication using the connection control circuit independent of the particular protocol comprises TCP (Transmission Control Protocol) and IP (Internet Protocol).

已经公开了一种方法,作为这种不考虑电路连接控制的机制的例子,采用该方法,可以通过象TCP层这样的端口来监视来自应用程序的业务请求,并且通信终端设备基于业务请求的检测来建立到通信终端站的电路连接并且启动通信(例如,参见公开待审的日本专利申请公开文本第HEILL-340986号第0046-0050段)。 A method has been disclosed, as an example of a circuit which is connected to a control mechanism not considered, this method, such as a port through the TCP layer to monitor the service request from the application, and communication terminal device based on the service request is detected to establish a communication circuit connected to the terminal station and initiates communication (e.g., see Japanese Laid-Open Patent application Publication HEILL-340986 paragraph No. 0046-0050).

然而,如上所述的传统通信设备存在下述问题,即当应用程序指定了错误的端口号并请求业务时,通信终端设备检测业务请求的发出并且启动通信。 However, there is a problem of the conventional communication apparatus as described above, i.e., when the application specifies the wrong port number and requests service, the communication terminal device detects service requests made and start communication. 特别地,当通信终端设备使用象Linux这样的允许自由修改并且重新发布的OS(操作系统)时,可以想象到许多第三方将开发原始应用程序,并且当应用程序指定错误的端口号并仍然启动业务时,这会导致大的安全性问题。 In particular, when the communication terminal equipment such as Linux allows to freely modify and re-release of the OS (operating system), it is conceivable that many third parties will develop the original application, and specify the wrong port number when the application starts and still when the business, which will lead to a big security problem.

而且,采用传统通信设备,当应用程序在多个业务之间进行切换时,需要执行电信业务切换(切断一个业务,接着启动另一个业务)的电路连接控制,这已经成为应用开发者的沉重负担。 Moreover, conventional communication apparatus, when an application among a plurality of switching operations, the switching telecommunications services needs to be performed (cutting a service, then start another business) connected to the control circuit, which has become a heavy burden on application developers .

下面,将参照图2所示的时序图,说明如上构造的通信终端设备在启动数据传输时的操作。 Next, with reference to the timing chart shown in FIG. 2, the operation of communication terminal device constructed as above when starting the data transmission. 在下面的说明中,应用程序100是浏览器,通信协议500是HTTP,且在无线方案处理器400中所处理的无线方案是W-CDMA。 In the following description, the application 100 is a browser, the communication protocol 500 is a HTTP, and radio programs in wireless scheme processor 400 is processed by W-CDMA.

首先,在通信操作开始(例如,当拨号器200被激活时)之前,U平面监视器28 监视TCP/IP 600的所有端口(800)。 First, in the communication operation is started (e.g., when the dial 200 is activated) before, U planar monitor 28 monitors the TCP / IP for all ports 600 (800).

接着,当应用程序(浏览器)100开始发送用户信息时,将通信开始通知(communication start notification)802从应用程序(浏览器)100发送至通信协议500(HTTP)。 Subsequently, when the application (browser) 100 starts transmitting user information, a communication start notification (communication start notification) 802 sent from the application (browser) 100 to the communication protocol 500 (HTTP). 当通信协议500(HTTP)接收到通信开始通知802时,将通信开始通知804从通信协议500(HTTP)发送到TCP/IP 600。 Communication protocol 500 (HTTP) receiving the communication start notification 802 when the communication start notification 804 sent from the communication protocol 500 (HTTP) to TCP / IP 600.

接着,当U平面监视器280检测到从TCP/IP 600接收到通信开始通知804时,U平面监视器280从所发送的用户信息的报头中提取出目的端口号806。 Next, when the monitor 280 detects the U-plane to TCP / IP 600 is received from the communication start notification 804, the U-plane monitor 280 extracts the destination port number 806 from the header of the user information being transmitted.

顺便说明,此处,尽管U平面监视器280被构造成检测至TCP/IP 600的所有端口的数据传输,即从通信协议500(HTTP)到TCP/IP 600的数据传输,同样可以检测从TCP/IP 600到U平面处理器420的数据传输。 Incidentally, here, although the U-plane 280 is configured to monitor to detect TCP / IP data transmission of all ports 600, i.e., data transmission from the communication protocol 500 (HTTP) to TCP / IP 600, the TCP can be detected from the same / IP data transfer to the U-plane 600 of the processor 420.

为检测从通信协议500(HTTP)到TCP/IP 600的传输,可以检测在较早阶段中的用户信息传输的开始。 It is detected from the communication protocol 500 (HTTP) transport TCP / IP 600 to, start transmission of user information can be detected at an early stage. 而且,当检测从TCP/IP 600到U平面处理器420的传输时,U平面监视器280只监视一个端口以减少处理负荷。 Further, when detecting a transmission from a TCP / IP 600 to 420 of the U-plane processor, 280 U-plane monitor monitors a port to reduce the processing load.

接着,将U平面监视器280所提取的目的端口号808输出至端口号检验器260。 Next, the U-plane destination port number 808 monitor 280 outputs the extracted port number to the checker 260. 当目的端口号808被输出时,端口号检验器260参照如图3所示的端口号DB 270,检验该目的端口号808是否是适当的端口号。 When the destination port number 808 is output, the port number checker 260 with reference to the port number DB 270 shown in FIG. 3, the test object 808 is an appropriate port number port number. 更具体地说,将目的端口号808与端口号DB 270中存储的端口号进行比较,当存在匹配的端口号时,则确定该目的端口号808是适当的,而当不存在匹配的端口号时,则确定该目的端口号808是不适当的。 More specifically, the destination port number 808 is compared with the port number that is stored in DB 270, when there is a matching port number, it is determined that the destination port number 808 is appropriate, and when there is no matching port number when it is determined that the destination port number 808 is inappropriate.

此处,当确定目的端口号808是不适当的端口号时,将该结果通知给拨号控制器210,拨号控制器210拒绝通信。 Here, when it is determined that the destination port number 808 is a port number inappropriate, the controller 210 notifies the dial, dial deny traffic controller 210. 采用这种方法,就可以防止除应用程序100(浏览器)以外的其它应用程序启动非法连接,从而提高安全性。 With this method, it is possible to prevent the illegal connection 100 in addition to other applications than the application (browser) starts, thereby improving safety.

而且,当确定目的端口号808是适当的端口号时,则将C平面连接请求810从端口号检验器260输出至拨号控制器210。 Further, when it is determined destination port number 808 is the proper port number, then the connection request C-plane checker 810 output port number 260 from the controller 210 to dial. 接着,拨号控制器210将如下执行C平面处理。 Next, the controller 210 will dial C-plane processing performed as follows.

首先,将连接信息请求812发送到连接信息管理器220,连接信息管理器220参照如图4所示的连接信息DB 230以获取连接信息。 First, the connection information request message 812 to the connection manager 220, connection information manager 220 refers to the connection information DB 230 shown in FIG. 4 for the connection information. 此处,从如图4所示的连接信息DB 230中获取W-CDMA无线方案和基于PDCP(分组数据会聚协议)的IP(IP over PDCP)的承载(bearer)。 Here for W-CDMA and wireless solutions based on IP (IP over PDCP) PDCP (Packet Data Convergence Protocol) of the carrier (BEARER) from the link information DB 230 shown in FIG. 4. 接着,将所获取的连接信息814发送至拨号控制器210。 Subsequently, the acquired connection information 814 transmitted to the dial controller 210.

接着,拨号控制器210将状态建立请求816发送至状态管理器240,状态管理器240检验电路连接状态,当不存在电路连接时,在状态DB 250中设置象“应用程序100(浏览器)正在发送分组交换呼叫”这样的通信状态。 Next, the dial controller 210 transmits status setup request 816 to the state manager 240, the state manager 240 check circuit connection state, when the circuit connection does not exist, in the state DB 250, and is provided as "application 100 (browser) is transmitting a packet switched call "this communication state. 接着,将已完成状态建立(818)的结果通知给拨号控制器210。 Subsequently, to establish the completed state (818) of the controller 210 notifies the dial.

而且,拨号控制器210向呼叫处理器300发送与连接信息814相应的C平面连接请求,并且在呼叫处理器300的CS处理器310和PS处理器320中执行预定处理。 Further, dial call processor 300 to the controller 210 transmits the connection information 814 corresponding to the connection request C-plane, and performs a predetermined process in the processor 300 call processor 310 CS and PS processor 320.

接着,拨号控制器210发送分组交换呼叫的C平面连接请求820,PS处理器320控制无线方案处理器400中的C平面处理器410并且执行分组交换呼叫的C平面连接。 Next, the controller 210 transmits the C-plane dial packet-switched call connection request 820, PS processor 320 controls the C-plane processor 410 and the processor 400 performs a wireless scheme C-Plane packet-switched call connection. 于是,当完成C平面连接时,将连接完成通知822发送至拨号控制器210。 Thus, upon completion of the C-plane connection, the connection completion notice 822 sent to the dial controller 210.

接着,拨号控制器210向状态管理器240发送状态建立请求824,状态管理器240在状态DB 250中设置象“应用程序100(浏览器)正在发送分组交换呼叫”这样的通信状态。 Next, the controller 210 establishes the dial-transmission state manager 240 requests the state 824, the state manager 240 in the state DB 250, and is provided as "application 100 (browser) is sending a packet-switched call" This communication state. 接着,将状态建立已完成(status setup iscomplete)(826)的结果通知给拨号控制器210。 Next, the state of establishment has been completed (status setup iscomplete) (826) of the controller 210 notifies the dial.

于是,就完成了C平面中的处理,拨号控制器210将C平面连接已完成(C-plane connection is complete)(828)的情况通知给U平面监视器280。 Thus, the processing is completed in the C-plane, C-plane Call Controller 210 connection is completed (C-plane connection is complete) (828) notifies the U-plane of the monitor 280. 接着,当U平面监视器280将数据传输开始通知830输出到TCP/IP 600时,通过U平面处理器420开始用户信息的传输。 Then, the output of the monitor 280 when the U-plane data 830 to the transmission start notification 600, transmission of information by the user U-plane processor 420 starts TCP / IP.

接着,根据本实施例,监视用户信息的传输。 Next, according to the present embodiment, the monitoring of the transfer of user information. 即监视U平面中的数据传输,并且当检测到数据传输时,执行关于数据报头中包含的目的端口号是否是合法(authorized)的适当端口号的检验,只有当该端口号是适当的端口号时才开始通信,以便能够防止指定非法目的端口号的数据传输,从而提高安全性。 I.e., monitoring the data transmission the U-plane, and when detecting the data transmission, performs check for proper port number to whether the destination port number of a data packet included in the header is valid (Authorized) only when the port number is the appropriate port number when communication is started, so that is possible to prevent illegal destination port number designated data transmission, thereby improving safety.

顺便说明,尽管第一实施例被如下构造成:端口号检验器260执行端口号检验以便允许用户信息的传输,状态管理器240检测电路连接状态,以及当不存在电路连接时执行C平面连接,但是很容易想到,其中状态管理器240采用端口号检验器260的功能(通信许可批准功能(communication permitauthorizing function))的构造也能达到相同的效果。 Incidentally, although the first embodiment is configured as follows: Port number checker 260 performs a port number so as to allow inspection of the transfer of user information, the state manager 240 is connected state detecting circuit, and performing C plane is connected when the circuit connection does not exist, However, it is easy to think of, wherein the state manager 240 and a port number checker function 260 (licensed approval communication function (communication permitauthorizing function)) can be configured to achieve the same effect.

而且,尽管根据第一实施例,由拨号器200执行的通信许可批准功能是利用端口号进行的安全检验,但是很容易想到,其中呼叫处理器300容许多个电路连接(多呼叫支持结构),且状态管理器240比较所容许的电路连接数和当前电路连接数以允许新的电路连接的构造也能进行关于通信许可的各种判决。 Further, although according to the first embodiment, the license approved by the communication function 200 performs dialing is to use security check port number, it is easy to think of, wherein a plurality of call processor 300 permit electrical connection (multiple call support structure), and the state manager 240 compares the number of electrical connections and allow the circuit connected to allow current number of new construction circuit can be connected to various decision regarding the communication permission.

(第二实施例)在本实施例中,将说明图1所示的通信终端设备的操作,其中应用程序100包括多个应用程序,以及交换应用程序提供的业务。 (Second Embodiment) In the present embodiment, will be described operation of the communication terminal apparatus shown in Figure 1, where the application 100 comprises a plurality of applications, and applications provided by the service switching. 因此,根据本实施例的通信终端设备的结构与图1所示的结构相同,将省略对其的说明。 Thus, the configuration of a communication terminal apparatus and the present embodiment is the same as a structure, description thereof will be omitted.

图5是说明根据本实施例的通信终端设备操作的时序图。 FIG 5 is a timing diagram illustrating a communication terminal apparatus according to the present embodiment is operated. 在以下的说明中,应用程序100的应用程序从浏览器(即一种分组交换业务)切换到数据分配业务(即一种电路交换业务),并且浏览器所采用的通信协议500是HTTP。 In the following description, the application program 100 is switched from the application browser (i.e. A packet switched service) allocated to the data traffic (that is, a circuit switched service), and the communication protocol used by the browser 500 is HTTP.

首先,假设应用程序100(浏览器)使用通信协议500(HTTP),并且利用基于PDCP的IP(IP over PDCP)来执行内容获取(content acquisition)900。 First, assume that application 100 (browser) using a communication protocol 500 (HTTP), and be performed using the IP PDCP-based (IP over PDCP) acquires content (content acquisition) 900. 例如,当通信终端设备的用户点击应用程序100(浏览器)的菜单时,则确定应用程序100(数据分配(data distribution))的开始。 For example, when 100 (browser) of the user clicks the menu application communication terminal device starts the application 100 (data distribution (data distribution)) is determined.

接着,将数据分配业务开始(data distribution service startup)902从数据应用程序100(浏览器)发送到应用程序100(数据分配)。 Next, the data distribution service starts (data distribution service startup) 902 transmits data from the application 100 (browser) to 100 (data distribution) applications. 应用程序100(数据分配)接收数据分配业务开始902,并且将数据分配业务的连接请求904发送到拨号控制器210。 Application 100 (data distribution) 902 begins receiving traffic data distribution, data distribution service and the connection request is sent to the Call Controller 904 210.

接着,拨号控制器210向连接信息管理器220发送连接信息请求906,该连接信息请求906包含指示强制连接的参数,并且从连接信息DB 230中获取连接信息。 Next, the controller 210 dial 220 sends connection information to the connection information request manager 906, the connection request message 906 contains an indication of the forced connection parameter, and acquires the connection information from the connection information DB 230. 例如,获取基于UDI(非受限数字信息(Unrestricted DigitalInformation))的PPP(PPP over UDI)作为承载,并且将所获取的连接信息908发送给拨号控制器210。 For example, based on obtaining the UDI (unrestricted digital information (Unrestricted DigitalInformation)) the PPP (PPP over UDI) as the bearer, and sends the controller 210 to dial the acquired connection information 908.

接下来,拨号控制器210向状态管理器240发送状态建立请求910。 Next, the dial controller 910 sends a request 210 to establish a state manager 240 state. 假如应用程序100(浏览器)正在发送分组交换呼叫,这时状态管理器240参照状态DB 250,例如,将象“应用程序100(浏览器)正在发送分组交换呼叫”这样的通信状态912返回给拨号控制器210。 If the application 100 (browser) is sending a packet-switched call, time status manager 240 refers to the status DB 250, for example, as "the application 100 (browser) is sending a packet-switched call" This return to the communication state 912 dial 210 controller.

由于应用程序100(浏览器)正在发送分组交换呼叫,拨号控制器210执行切断该连接的C平面处理。 Because the application 100 (browser) is sending a packet switched call, the controller 210 performs dial-cutting C-plane processing the connection.

即将分组交换呼叫切断请求914发送至呼叫处理器300,由呼叫处理器300的PS处理器320执行预定处理,切断分组交换呼叫的传输,并且将切断完成通知(cut completion notification)916返回给拨号控制器210。 PS call disconnection request is about 914 transmits to the call processor 300, call handler 320 is executed by the processor 300 PS predetermined processing, cutting off the transmission of a packet switched call, and the cut completion notification (cut completion notification) 916 control returns to the Dial 210.

当接收到切断完成通知916时,拨号控制器210再次向状态管理器240发送状态建立请求918,状态管理器240在状态DB 250中设置象“应用程序100(浏览器)的分组交换呼叫已被切断”这样的通信状态。 Upon receiving the disconnection completion notification 916, the controller 210 establishes dial again transmits STATUS manager 240 requests 918, the state manager 240 in the DB 250, and the packet status provided as "application 100 (browser) has been switched call oFF "state such communication. 接着,将完成状态建立(status setup is complete)(920)的情况通知给拨号控制器210。 Next, a case will build completion status (status setup is complete) (920) the controller 210 notifies the dial.

响应于此,将分组通信切断完成通知922从拨号控制器210发送至应用程序100(浏览器),应用程序100(浏览器)进入空闲状态,拨号控制器210向状态管理器240发送状态建立请求924以启动用于应用程序100(数据分配)执行的数据电信业务的电路交换呼叫,状态管理器240在状态DB 250中设置象“应用程序100(数据分配)正在发送电路交换呼叫”这样的通信状态。 In response thereto, the communication disconnection completion notification packet 922 transmitted from the controller 210 to dial the application 100 (browser), the application 100 (browser) to the idle state, the controller 210 establishes dial-up request to the manager 240 transmits STATUS 924 to start the data for telecommunication service 100 (data distribution) executing an application circuit switched call, the state manager 240 "sending application circuit 100 (data distribution) switched call" state DB 250, and a communication setting like this status. 接着,将完成状态建立(status setup is complete)(926)的情况通知给拨号控制器210。 Next, the case of establishing the completion status (status setup is complete) (926) the controller 210 notifies the dial.

而且,拨号控制器210发送与已获取的连接信息908相对应的C平面连接请求928,呼叫处理器300中的CS处理器310和PS处理器320各自执行预定处理。 Further, the controller 210 sends a dial acquired connection information 908 corresponding to the C-plane connection request 928, the processor 300 call processor 310 of the CS and PS processor 320 each execute a predetermined process. 此处,例如,拨号控制器210发送电路交换呼叫的C平面连接请求928,CS处理器310控制无线方案处理器400中的C平面处理器410执行C平面连接。 Here the C-plane, for example, the controller 210 transmits circuit-switched dial-up a call connection request 928, CS processor 310 controls the wireless scheme C-plane processor 400 of the processor 410 executes the C-plane connection. 当完成C平面连接时,将连接完成通知(connection completionnotification)930发送至拨号控制器210。 Upon completion of the C-plane connection, the connection completion notification (connection completionnotification) 930 is sent to the dial controller 210.

接着,拨号控制器210通知应用程序100已完成到应用程序100(数据分配)的电路交换呼叫的连接,而将状态建立请求934发送至状态管理器240,状态管理器240在状态DB 250中设置象“应用程序100(数据分配)正在发送电路交换呼叫”这样的通信状态。 Next, the dial controller 210 notifies the application 100 has finished the connection to the application 100 (data distribution) of the circuit switched call establishment request 934 and the status is sent to the state manager 240, the state manager 240 is provided in the state DB 250, and like "100 (data distribution) applications are driving circuit switched call" this communication state. 接着,将完成状态建立(status setup iscomplete)(936)的情况通知给拨号控制器210。 Next, a case will build completion status (status setup iscomplete) (936) the controller 210 notifies the dial.

采用这种方法,应用程序100(数据分配)接收数据分配业务(基于UDI的PPP),并且开始内容获取(connect acquisition)938。 With this method, applications (data distribution) 100 receives data distribution services (UDI of the PPP-based), and starts the content acquisition (connect acquisition) 938.

于是,根据本实施例,当通信终端设备具有多个应用程序并且切换应用程序所进行的业务时,每个应用程序可以在不考虑其它应用程序的通信状态的情况下,单独完成和启动通信,以便可以自动执行业务切换。 Thus, according to the present embodiment, when the communication terminal apparatus having a plurality of switching applications and business applications carried out, each application can be made without consideration of other applications of the communication state, the individual complete and initiate communication, so that the switching operations may be performed automatically.

尽管利用第二实施例说明了从分组交换业务(基于PDCP的IP)到(基于UDI的PPP)的业务切换,但是可以很容易地想到,在象从电路交换业务到分组交换业务这样的不同切换业务之间的切换,以及切换到相同切换业务的不同承载业务(从电路交换业务到电路交换业务,从分组交换业务到分组交换业务等)都是可以的。 Although the second embodiment illustrates the use of a service handover from a packet switched service (PDCP-based IP) to (based on the UDI PPP), but can easily occur in such as various handover from a circuit switched to a packet switched service traffic switching between operations, and switching to the same service in different switching bearer traffic (traffic from circuit-switched to circuit switched services, packet-switched services to the packet-switched services, etc.) are possible.

尽管利用第二实施例说明了多应用程序的业务交换,但是可以很容易地想到,相同的结构使一个应用程序能够在多个业务之间进行切换。 Although the second embodiment illustrates the use of services switching multiple applications, but can easily occur, the same structure is possible for an application to switch between a plurality of services.

尽管第二实施例被如此构造,以便将包含指示强制连接的参数的连接信息请求用作从应用程序到拨号器200的请求业务交换的命令,但是可以很容易地想到,即使在命令指定标识当前连接且不需要切断的业务的标识符的情况下,相同结构也能启动业务切换。 Although the second embodiment is so constructed so as to contain the connection information indicating parameter as a force connection request command from the application service request to the dialer 200 exchanged, but can easily occur, even if the current command identifier specified in the case where the connection and does not require disconnection of the service identifier, the same configuration can start service switching.

而且,尽管上述实施例被构造成使用TCP/IP,通过监视TCP/IP的所有端口并且检验报头中包含的端口号是否适当,但是使用UDP/IP同样也可以达到相同的效果。 Further, although the above embodiment is configured to use TCP / IP, by monitoring all the ports of TCP / IP packet and checks the port number included in the header is appropriate, but the use of UDP / IP can also achieve the same effect. 尽管根据HTTP通信协议来进行说明,但是也可采用任何包括象SIP(Session Initiation Protocol,会话启动协议)这样的IP信令协议的协议,其中SIP协议使用TCP/IP(UDP/IP)和H.323。 Although will be described according to the HTTP protocol, but may be employed include any such IP signaling protocols like SIP (Session Initiation Protocol, Session Initiation Protocol), wherein the SIP protocol using TCP / IP (UDP / IP) and H. 323.

尽管已经说明上述实施例被构造成在拨号器检测到用户信息传输的开始之后,利用C平面处理来建立连接,即由U平面处理的启始来触发C平面处理,但是在已利用C平面处理建立连接之后,上述实施例中所述的拨号器能够操作以启动发送用户信息的U平面处理。 While there has been described, after the above-described embodiment is configured in the dialer detecting the start of transmission of user information, the use of C-plane processing to establish a connection, that is processed by the U-plane start to trigger C-plane processing, but the plane of processing is by C after the connection is established, the above-described embodiments of the dial operable to initiate transmission of the user information U-plane processing.

如上所述,本发明能够在无需执行复杂的电路连接的应用程序的情况下执行顾及安全性的数据通信和业务交换。 As described above, the present invention can be performed taking into account security and data communications services switching without the need to perform complicated application circuit connection.
